Picnic Tap, clean or rinse after every use?

[thisispants]

I've just started kegging and had my first beer from the keg today, bloody lovely!!

However, should I clean or rinse the picnic tap after every use?

No leave connected to the keg and just spray some sanitiser up the spout.

Beat me to it Grott.
